MIRI Imaging Target Acquisition

Target acquisition (TA) is generally not required for MIRI imaging =
observations. For the special case of high precision photometry of bright sources, such as=
time-series observations (TSOs), TA may be desired.

The MIRI imager can be used to obtain high precision photometry of brigh=
t sources that may be useful for time-series observations (TSOs). Given the=
high stability and photometric precision required for such observations, t=
arget acquisition (TA) is usually recommended to ensure that the target is =
very accurately placed in the nominal pointing position for the required su=
barray. This is particularly important for repeated observations, where dif=
ferent exposures will be combined.

TA for MIRI imaging is not currently supported, but is expected to be av=
ailable in the future.
